This is the project home page of the SmaTrig 2. 1, the improved version of the the SmaTrig 2. On this site you will find complete instructions how to use and build the versatile and compact (27 gram) 15-in-1 camera trigger SmaTrig 2. 1. Everything needed to build the device is provided including the PCB design, firmware, drill plans, etc. The SmaTr

ig 2. 1 is based on an AVR microcontroller, and is equipped with sensor circuitry for detecting sound and light pulses for capturing lightnings or high-speed photography. The 15 functions can be divided into four groups: bulb mode bracketing programs for HDR photography, interval and timer modes, sensor modes and other functions like manual camera triggering or configuration. Many of the modes have some hidden advanced options, but I paid great attention not to obscure their usability. Ritual instruction manual spurners can use the SmaTrig just using their intuition. The SmaTrig 2. 1 controls the camera using a remote release cable, or in a wireless way per IR signal. There is no need to modify the camera in any way to use the trigger. The various sound or light trigger functions use either the integrated photo diode for light detection, or an external microphone that can be plugged into the sensor connector. Flash units can also be connected to the trigger directly to allow high-speed photography. The functions of the SmaTrig are devided into two groups. The functions with a black symbol on the label don`t need a time specification and are started usually with just one button press. The functions with a red symbol, e. g. intervall or long exposure need a time specifiction. The time is set by pressing the button several times according to this table (printed also on the trigger label): To overcome the +-2 EV bracketing...
